Lafarge Cement and Flyash Silos

SHARE THIS

Project Overview

PCL self-performed the slipforms and placement of two new silos: a 10,000-tonne cement and a 4,000-tonne flyash at Lafarge’s cement plant in Richmond. The work began with dewatering the site by re-injecting the ground water to avoid river water contamination. Next, the team poured a 1,800-cubic-meter raft poured with Lafarge’s Agilia®, self-leveling and self-placing concrete. The pour for the two, 31-meter high silos was continuous over six days, at a production rate of 200 mm/hour. Structural steel work included silo roofs, a railcar unloading building, bucket elevator stair tower, cement transfer bridges, rail slides, surge bin modifications, and under hopper work platforms. All work was performed in an operating facility.

In 1997, PCL completed an expansion at the Richmond Lafarge site, building a new cement plant and doubling the facility’s manufacturing capacity.
